Although it was lunch time when I stopped in a couple months ago, a few of you did get to see the super-bright LED ring. I&rsquo;ll probably make an Instructable out of that project and I&rsquo;ll be pointing people here to buy the parts, so you may want to make sure you can get more if nothing else (alternative: reveal your secret source!)</p>N.Poole on COM-08203 - Luxeon Portable LED - White 1 Watt (Sale)N.Pooleurn:uuid:cf922ebc-7bb5-e28b-5d48-0332548fdc322010-11-03T14:12:01-06:00<p>Agreed, these things are really spectacular for their size. Also, if you&rsquo;ve done a little bit of SMD soldering in the past, you&rsquo;ll have no problem with these. The only issue is that they do get very warm, as 15504 mentioned, also if you melt one with your soldering iron (As I did) it will short, so it stands to reason that if you left it on long enough it would heat itself up until it shorted, then melt itself free of it&rsquo;s solder pads, lol. (I&rsquo;m gonna blink mine with a tiny IC to avoid the heat problem altogether)<br/>
They&rsquo;re the only thing that will work for my application and i think they&rsquo;re great, pick a few up just for the novelty.</p>Customer #15504 on COM-08203 - Luxeon Portable LED - White 1 Watt (Sale)Customer #15504urn:uuid:6b0f75e4-2d01-1525-98ca-7b35a7976a7e2007-02-24T21:32:47-07:00<p>These are really neat little LED&rsquo;s. Very bright and can be powered briefly by a small 3.7volt lithium cell. They must be soldered to a surface that will sink heat quickly like a PC board with fairly heavy cladding if using them this way or they will melt the solder holding them down. A proper LED driver should be used or a resistor at minimum to keep the current below 400mA or heat willl be a problem. A cluster of these will eat up some excess current and 3 or 4 produce quite a bit of bright white light. Dazzling really. Defiletely the smallest high powered LED. For the price there&rsquo;s nothing I&rsquo;ve seen especially in such a small package that outputs as much light until you get to the 3 watt class.</p>
